Thirteen is what percent of 23: A Comprehensive Guide to Calculating Percentages

Percentages are an essential concept in mathematics, and understanding how to calculate them is crucial for various real-world applications. In this article, we will delve into the world of percentages and explore the concept of finding a percentage of a given number. We will use the example of "thirteen is what percent of 23" to illustrate the steps involved in calculating percentages.

What is a Percentage?

A percentage is a way of expressing a value as a fraction of 100. It is denoted by the symbol "%" and is calculated by dividing the value by the total and multiplying by 100. For example, if we want to find 25% of 100, we would calculate (25/100) * 100 = 25.

Calculating Percentages

To calculate a percentage of a given number, we can use the following formula:

Percentage = (Value / Total) * 100

Where:

Value is the number we want to find the percentage of
Total is the total number we are finding the percentage of

Step-by-Step Guide to Calculating Percentages

Let's use the example of "thirteen is what percent of 23" to illustrate the steps involved in calculating percentages.

Identify the value and total: In this case, the value is 13 and the total is 23.
Divide the value by the total: Divide 13 by 23 to get 0.5652173913 (rounded to 6 decimal places).
Multiply by 100: Multiply 0.5652173913 by 100 to get 56.52173913 (rounded to 6 decimal places).
Round to the nearest hundredth: Round 56.52173913 to the nearest hundredth to get 56.52%.

Answer

Based on the calculations above, we can conclude that 13 is approximately 56.52% of 23.
